I have an 90 mx-6 turbo 4ws which makes a buzzing sound after starting. Sometimes it's a small buzz and other times it's of a longer duration. It sounds like it's coming from behind the dash board somewhere. Any ideas?

it could be the ABS pump doing it's self testing routine. I think that the owner's manual talks about it.

Yep it's the ABS pump pressurizing the accumulator. Normal behavior.

OK, thanks. Is it normal for it to occasionally check itself when driving? Sometimes it buzzes for one or two seconds during normal driving.

Mine does the exact same thing, buzzes when the car started and then sometimes once in a blue moon it does it about 30 seconds later. Very anoying though!
